Which transgenic human protein product, developed using rDNA technology, is utilized for the treatment of emphysema?

α-1 antitrypsin

The correct answer is Option (1) -α-1 antitrypsin

Transgenic animals can be used to produce valuable biological products, such as human protein α-1-antitrypsin, which is used to treat emphysema.

Medicines required to treat certain human diseases can contain biological products, but such products are often expensive to make. Transgenic animals that produce useful biological products can be created by the introduction of the portion of DNA (or genes) which codes for a particular product such as human protein (α-1-antitrypsin) used to treat emphysema.

Transgenic animals are organisms whose genetic makeup has been altered to include specific genes or DNA from other species. This genetic modification is achieved through recombinant DNA (rDNA) technology, where the desired gene is introduced into the animal's genome.
